I’m trying to use 1.4 SDK and I’ve already configured the workspace to use it. But I’m getting the error below running a simple hello world program but works fine if I use 1.5 SDK. Am I missing something 😕

If you want that your project work in 1.4 and 1.5 then you have to set project propertiy (java compiler) to 1.4
